    It is easier, at least for a novice, to fit a metal tray to a model than to a mouth. Ex- perienced practitioners can readily fit it to the latter. But whichever way you do it, fit your tray thus, to within an eighth of an inch of the gums all around; and always shy of the attacli- hig muscles of the li]) and cheek, so the metal won't strain them in the least. Don't let your metal tray run up high he- hind the tuberosities so as to strain the tissues there. Bear in mind, 1 repeat, i/our metal tray mustn't .strain the tissues ani/ichere; espeeiall// not the muscular tissues. (Stick a pin in that essential fact.) After long effort. 1 liave succeeded in getting some Greene-Method trays made on purpose for those who may learn their advantage. There are for the present ten in a set; and so shallow in depth, and otherwise so shaped, as to re- quire a minimum of change. They are manu- factured by the Detroit Dental ^Manufacturing Coni]^any, Detroit. Mich. While you can cut your old trays down and shape them, as I show you, yf)u can get more appropriate new ones. Ours have removable handles, the advantages to be shown later on. THE FITTED METAL TRAY. Xow you have fitted your metal tray, either to the approximate model or to the mouth it- self, in a way to leave space*room for your com- pound to hide it (the tray) when your correct- able impression is first taken. That is. the im- pression material must cover the metal trays all over. The metal can't be mani])ulated: the material can be—one reason for l()w=riinined travs.
